Typical Temperature

The temperature dependencies of the bandwidths for self-trapped exciton emission spectra in several alkali halide crystals with high temperature of thermal quenching for self-trapped exciton emission (NaBr, KI, CsI) have been studied and compared with a typical temperature behavior of Auger-free luminescence spectra. It was shown that different phonon modes are responsible for broadening of emission band for different types of self-trapped excitons as well as for different bands in the spectrum of Auger-free luminescence. The features found indicate that the lattice structure of emitting state for Auger-free luminescence has most probably the on-center character.

Photon Counting Mode

A digital technology for scanning the X-ray luminescence, tunnel luminescence, and thermostimulated luminescence spectra in the spectral range from 200 nm to 850 nm is experimentally demonstrated using the example of a NaCl crystal, which is part of the group of alkali halide crystals. This is done with the specified spectrum intervals and scanning speed using a high-aperture monochromator MSD-2 and a photoelectronic multiplier type H 8259 of the company “Hamamatsu”, operating in the photon counting mode, controlled by special programs SpectraScan and ThermoScan. The obtained experimental data are digitally converted for further processing of the graphical representation of the results using the OriginPro software package, which allows you to draw up graphical dependencies of the spectra and perform their mathematical processing.
